N型冷凝泵

N型冷凝泵

N型冷凝泵系單級單吸懸臂式離心冷凝泵,用來抽送冷凝器中的凝結水和750~3000kw汽輪發電機組抽送凝結水或物理、化學性質類似於水的其他液體之用。

產品介紹


目前最廣泛的在電廠使用,液體溫度不超過80℃。泵進口壓力不高於0.6MPa。
N型冷凝泵泵主要由泵體、葉輪、軸、懸架、泵蓋等部件組成。軸封採用軟填料密封。泵的旋轉方向從傳動方向看,泵為逆時針方向旋轉。其中該型號的凝結水泵軸承採用的是懸臂式的托架軸承支撐,當中裝有兩個滾動的軸承,這樣平衡了軸向力,軸承的潤滑採用的是油脂潤滑。
N型冷凝泵還帶有誘導輪,這種結構的凝結水泵結構緊湊、效率高、運行平穩,抗汽蝕性能好。在使用過程中嚴格按照使用說明進行。
